We wanted to know and find out how penguins keep warm in Antarctica. We discovered that penguins have blubber to help keep them warm. We did a science experiment using ice water and lard to test it! We had to put our hand in the ice water to see how long we could last with it - not very long! Then we put our hand in a bag of lard - we were able to keep our hand in the ice water for much longer with the lard around it.
